LJ12A3-4-Z/BX NPN 24V Inductive Proximity Sensor

This proximity sensor detects a metal object with a maximum distance of 4 mm from the sensor. The sensor works as an NPN transistor (normally open), which means that the voltage is cut off when a metal object is detected within 4 mm from the sensor. Specifications: Voltage: DC 24V  Output current: 300mA  Detection distance: 4mm  Polarity: NPN  Detection objects: Magnetic metals (if not magnetic metals, detection range is reduced) Wire type: 3 wire type (Brown, Blue, Black)  Dimension: app.5.7x2.5cm/2.24x0.98''
